Currently the async EQ has 256 entries only. It might not be big enough for the SW to handle all the needed pending events. For example, in case of many QPs (let's say 1024) connected to a SRQ created using NVMeOF target and the target goes down, the FW will raise 1024 "last WQE reached" events and may cause EQ overrun. Increase the EQ to more reasonable size, that beyond it the FW should be able to delay the event and raise it later on using internal backpressure mechanism.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
